Applications:

Polyoxyethylene sorbitan monolaurate is a class of nonionic surfactants with emulsification, diffusion, solubilization and stabilization.

1) It is widely used as emulsifier, dispersant, solubilizer, stabilizer and so on in pharmaceutical, daily chemical, food and textile industries. As a emulsifier, the high concentration of electrolyte and the change of pH value have little influence on its emulsifying ability.

2) It is a good class of oil / water type emulsifier. When preparing oil / water emulsifier, it is often used in combination with dehydrated ester, and the emulsion has better stability. By changing the type and amount of emulsifier used together, the water / oil type or oil / water type emulsion and cream with different texture and consistency can be produced.

3) Due to the good emulsification, dispersion and solubilization of various oils, such as mineral oil, vegetable oil and animal oil, this kind of excipient is mainly used in the manufacture of a variety of liquid preparations, such as perfume, mixture, lotion, emulsion, etc., and semisolid preparations (such as ointment, cream, suppository, etc.). Sterile and sterile preparations (such as eye drops, eye ointments, injections, etc.). When choosing this kind of excipients, we should pay special attention to safety in addition to the factors such as the stability of the preparations.

TW20 has the above functions and uses. It is determined by concentration, and generally uses 0.1 to 2%.
